What are paraplegia, quadriplegia, and tetraplegia?
Paraplegia is paralysis from approximately the waist down. Quadriplegia, or tetraplegia, is paralysis from approximately the shoulders down. Slightly more than half of spinal cord injuries result in quadriplegia. After age 45, the proportion increases markedly. It has been reported that 92% of all sports injuries result in quadriplegia.
